I don't know about that. Granted, I work largely within the intra-carrier/intra-industrial space, not so much with end-user endpoints, but to me it seems UDP is still the overwhelming norm.
In that space I would assume that SIP over TLS is mandatory. Anything else is a big security risk to users. If carriers exchange SIP requests over the Internet over UDP, they should be sued for not protecting their customers privacy.
Actually became quite common deployment here to use TLS from end user to an edge proxy and then switching to private network (or vpn) for core network routing, where UDP is still used given its lightweight design and native async communication.
I agree that a professional service should not use anything than TLS on public internet, but there is still a lot of demand for UDP for private links.
